Its a fan-made Half-Life game that plays like a top down shooter. Its supposed to have randomly generated levels and play like a roguelike, but it only features one level (Questionable Ethics) and ability to load your own levels you can make in Hammer.

Its an indie immersive sim, set in a dystopian city. Just like in something like Deus Ex, you can have different approach to a single task, and one of them is punching the bad guys in the face, because this game has more focus on the melee combat.

Its an indie game, developed by a single person, and its probably the first Quake II-like (or at least the first I've ever played). Unlike other games, it tries looks retro, models are low poly, textures are low res and the cutscenes look like something from a mid-late 90s videogame and it play like one.

Its a total remake of 1994 classic, in which you play as the hacker, who got arrested and promised some implants if he'll do a dirty job for the corpos. The UI and combat has been modernized, while the layout of the Citadel Station has remained exactly the same. The graphics while pixelated, are still better than those in 1994, thanks to full 3D and Unreal Engine 4.

Its a Duke Nukem-like, where you play as a badass woman, who exterminates insectoid alien bastards that shot her ride. It has kickass main theme, it has one liners, it has explosions and good gunplay and it has Duke himself (as an easter egg).

Its a cutesy metroidvania, where you play as a sword-wielding fish. Whatever you're expecting from a metroidvania is there: nook and crannies to explore and items to collect.

Its a fast-paced shooter, where you play as the blood-hungry (literally) robot that kills demons for blood. Its not exactly a typical boomer shooter, since it has a lot of weird and unique stuff going on that you should try for yourself.
